The Er3+:Y3Al5O12, which is able to transform the visible light from solar light into ultraviolet light as an upconversion luminescence agent, was prepared by nitrate‐citrate acid and heat‐treated method. And then, a novel photocatalyst, Er3+:Y3Al5O12/TiO2‐ZnO composite, which could effectively utilize the solar energy, was synthesized by ultrasonic dispersion and liquids boil method. In succession, X‐ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the structural morphology of the Er3+:Y3Al5O12/TiO2‐ZnO composite. And the degradation performances were also tested by UV‐vis spectrum and Ion chromatograph. To inspect the photocatalytic activity of Er3+:Y3Al5O12/TiO2‐ZnO composite, the Azo Fuchsine dye as target organic pollutant was degraded under solar light irradiation. The key impact parameters on the photocatalytic activity of Er3+:Y3Al5O12/TiO2‐ZnO such as Ti/Zn molar ratio, heat‐treated temperature and heat‐treated time were studied. Otherwise, the effects of dye initial concentration, Er3+:Y3Al5O12/TiO2‐ZnO, solar light irradiation time and other organic dyes were also investigated. It was found that the photocatalytic activity of Er3+:Y3Al5O12/TiO2‐ZnO composite was superior to TiO2‐ZnO powder in the similar system. © 2012 American Institute of Chemical Engineers Environ Prog, 32: 697–704, 2013

The Er 3+ :Y 3 Al 5 O 12 , as an upconversion luminescence agent which is able to transform the visible part of the solar light to ultraviolet light, was prepared by nitrate citrate sol gel method. A novel solar light photocatalyst, Er 3+ :Y 3 Al 5 O 12 /TiO 2 -CeO 2 composite was synthesized using ultrasonic treatment. The X ray diffraction (XRD) and scanning election microscopy (SEM) were used to characterize the structural mor phology of the Er 3+ :Y 3 Al 5 O 12 /TiO 2 -CeO 2 composite. In order to evaluate the solar light photocatalytic activity of Er 3+ :Y 3 Al 5 O 12 /TiO 2 -CeO 2 composite, the Azo Fuchsine dye was used as a model organic pollut ant. The progress of the degradation reaction was monitored by UV-Vis spectroscopy and ion chromatogra phy. The key influences on the solar light photocatalytic activity of Er 3+ :Y 3 Al 5 O 12 /TiO 2 -CeO 2 were studied, such as Ti/Ce molar ratio, heat treatment temperature and heat treatment time. Otherwise, the effects of ini tial dye concentration, Er 3+ :Y 3 Al 5 O 12 /TiO 2 -CeO 2 amount, solar light irradiation time and the nature of the dye on the solar light photocatalytic degradation process were investigated. It was found that the solar light photocatalytic activity of Er 3+ :Y 3 Al 5 O 12 /TiO 2 -CeO 2 composite was superior to Er 3+ powder in the similar conditions.

The Er 3? :Y 3 Al 5 O 12 as an upconversion luminescence agent, which can transform visible light into ultraviolet light, was synthesized by nitrate-citrate acid and calcined method. Then, a novel photocatalyst, Er 3? :Y 3 Al 5 O 12 /TiO 2 -ZrO 2 , was prepared using ultrasonic dispersion and liquid boiling method. The samples were characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). In succession, the degradation process of organic dye was monitored by UVVis spectrum and ion chromatography for verifying the photocatalytic activity of Er 3? :Y 3 Al 5 O 12 /TiO 2 -ZrO 2 . The influences on its photocatalytic activity such as Ti/Zr molar ratio, heat-treated temperature, and time were studied.
